Abstract
An acoustic transducer comprising a housing, and first and second stacks of ransduction plates disposed within the housing for engaging opposed wall portions of the housing, the first and second stacks being adapted to be held in compression between the housing opposed wall portions. A threaded stud extends from the first stack to the second stack, and a nut is threadedly engaged with the stud and adjacent one of the stacks. Movement of the nut on the stud operates to move the stacks toward the housing walls, respectively, to compress the stacks, and operates to relax compressive force on the stacks to enable withdrawal of one of the stacks and replacement thereof.
